Mithlond is the Elvish name for the Grey Havens in J.R.R. Tolkien’s writings. The name is Sindarin and means “Grey Havens” or “Grey Harbour.”
The Grey Havens are located on the Gulf of Lhûn in western Middle-earth. They are a major Elven port, traditionally associated with Círdan the Shipwright, who oversees the building and departure of ships.
At the end of The Lord of the Rings, Frodo, Bilbo, Gandalf, Galadriel, Elrond, and other travelers leave Middle-earth from the Grey Havens. Their ships sail west toward the Undying Lands, although the mortal hobbits are granted a special passage.
Mithlond should not be confused with Edhellond, another Elvish haven in southern Gondor, or with Rivendell and Lothlórien, which are inland Elven settlements. The English name Grey Havens and the Sindarin name Mithlond refer to the same important western port.
